MAP-CASE.

inattesa A Application led April 7,

To all 'whom t may concern Be it known that we,` JoHNF. PiLGRiM and WiLLiAM A. NiMMnn, citizens of the United States, residing at Two Rivers, in the county of Manitowoc and State of Wisconsin, have invented certain new and useful Improvements in Map-Cases, of which the following is a specification.

This invention relates to`holders for maps, charts or otherarticles of displayand more particularly to that type of holder designed to accommodate and receive a plurality of rollers and permit the same to be operated whereby the map, chart, or other article may be withdrawn from said holder for inspection and returned. i

The primary" object of the invention resides in the construction :of a holder for receiving a pluralityof spring rollers therein and which may be mounted ori-a support oi' attached to a wall for instance in such'position as to enable one to operate any one of said rollers to withdraw the map or other article rolled thereon including means for maintaining the roller supporting drum stationary when any one of the rollers is operated.

Another and very important object of the invention resides inthe construction of a simple, yet practical and highly efficient type of holder for maps, charts or articles of display 'whereby the same may be easily and quickly drawn out of the holder for exhibition and readily returned, andV which will permit any desired map or article to be drawn out and exhibited and subsequently returned to permit another roller to be operated for a like purpose including spring controlled means for maintaining the roller supporting members stationary.

A further and continued object of the invention resides in the construction of a novel and improved holder of the type above set forth, which is extremely simple in construction, consisting of comparatively few parts therefor, inexpensive to manufacture, highly efficient in operation, practical in use, easily operable, durable in construction and capable of universal use in connection with various articles of display for commercial or exhibition purposes.

With these and other objects in view as will appear as the description proceeds, the invention comprises the novel features of Specification of Letters Patent. Patentd NV, 15, 19210 1921. serial No. 459,364.

construction,` accompanied by elements and arrangements of parts which will be more fully described in the following specification and-'set forth with Vparticular-ity in the sub- V ject matter being claimed and appended thereto, wherein :e y, t i

Figure 1 is an end elevation showing lthe hinged closure for the holder.l U y v Fig. isa front view thereof shown partly in section. y

4F ig. 3 isa view partlyin section of a spring roller.

Fig. 4L is an end View of one of the roller carrying drums.

Referring now to the drawings wherein like parts refer to similar parts 'throughout the specification, n 5 designates a rectangular rcasing'or holder, preferably constructed of 'wood or` similar material and adapted tobe attachedto a wall or supported by suitable brackets (not shown),`said casing or holder -being'provided with abottom closurey or cover 6 which is hinged as at 7 to its lower rear side whereby ready access nay be had to the interior as is readily understood.,

Supporting brackets 8,9 secured interiorly of the casing or holder and to the respective ends of the saine, carry the end bearings 10 in which are rotatably mounted the roller supporting heads 11, 12 which carry the map, chart, or article to be exhibited as clearly shown by Fig. 2 of the drawing.

The end spindles 13 which extend through the roller supporting heads 11 and 12 and are retained in the bearing above referred to, permit the said heads to rotate in either direction for conveniently bringing any one of the rollers subsequently to be referred to in position so that the article carried thereby may be withdrawn and exhibited.

The end heads 11 and 12 are of course provided with a plurality of apertures or bearings 14; spaced equidistant and near the periphery of the saine for receiving the end spindles 15, 16 of a spring roller designated in its entirety by numeral 17. Each of the spring rollers 17 have wound thereon the map, chart or other article to be displayed, the ends of said rollers being provided with the usual ratchet and dog mechanism 18, 19 in the ends of the roller.

The end head 12 is provided with a ratchet 20 on its outer face, the teeth 21 of which are adapted to coperate'with the hooked end secured to the casing and which preventsv the head 12 from rotating under normal conditions.

By this construction, it will be.` readily seen that as the flexible chainv depresses the lever 23 and raises the hooked end 22 from one of the teeth `of the ratchet wheel, the end roller supportin heads 11' and 12 may be rotated tobring t e desired spring roller `17 to a position whereby the` article carried thereby may bewithdrawn from the casing and exhibited as is well understood.

In the accompanying drawings, we have illustratedv our invention embodied'in one form by way'of example, and which in practice has been -found to be highly satisfactory in obtaining the desired results. It will be obvious however that other embodiments may be adopted and that various changes in the details of constructionmay lbe re- ','so-rted toy `by those skilled in the art without vdepartingi'rom `the spirit and scope of the invention. It is y 'furthermore understood that the invention isnot necessarily limited or restricted to the precise elements shown except in so far as such" limitations .are yspec'iiiedin the subject matter being claimed. n K Having shown `and described our invention, what we` now claim as new and desire to secure by Letters Patent of the United States is Y l. `A device of the class described Compris- Vingl a rectangular casing having a hinged bottom, roller supporting heads having end spindles journaled in the sides of the casing, a plurality Yof equally spaced spring rollers rotatably mounted near the peripheral edge of said head within said casing, a ratchet on o-neof said heads and spring controlled locking means attached to the casing cooperatlng with said ratchet to vprevent rotation of the heads when moved'to a selective position. y

2. A device of the classk described comprising a rectangular, closed casing having a hinged bottom, bearings carried by the ends and within said casing, roller supporting heads journaled in said bearings and having `a plurality of equally spaced spring rollers rotatably mounted'near the peripheral edge of said heads and operable in either direction, a ratchet on one of said heads and rotatable therewith, a spring controlled locking lever pivotally secured to the casing and coperating with the ratchet and a flexible chain' for releasing said locking means Vto permit rotation of said heads to move a selective spring roller to operative position.

In testimony whereof, We aliix our signatures hereto. e
